I would like to ask how to calculate the weight percentage of the reinforcement and
matrix for (a) glass fibre-reinforced epoxy composite and (b) carbon fibre-reinforced epoxy composites. Densities of glass fibre, carbon fibre, epoxy resin, and polyester resin are 2.54 g/cm^3, 1.8 g/cm^3, 1.2 g/cm^3, and 1.5 g/cm^3, respectively.
